Really? He has been critical of Kerry many many times, and is very supportive of Bush's War on Terror.
Don't let him fool you; he proudly proclaims his RAT affiliation on the Batchelor show and elswhere.
That's why it's so incongruous that Loftus is a big Dem and friend of Joe Wilson -- he's proudly proclaimed both many times.
Actually I haven't heard Loftus criticize Kerry, but I don't listen every night and might have missed it. But you are correct that he's been supportive of Bush in the war on terrorists.
